Numerical study of Single-turn and Multi-turn coil effect in the induction heating process

Abstract

Induction heating has an important role in the industrial applications. Atypical induction heating system has three main parts where they are electricalsource, the RF-coil and work piece. The RF-coil is one of the importantparameters in setup of induction heating system. In this paper, we have beenstudied two kinds of coil (Single-turn and Multi-turn) using Finite ElementMethod (FEM) and by COMSOL MULTIPHYICS package. The results showthat considering of each of this coil has significant effect on theelectromagnetic fields, eddy currents and generated heat in the coil and workpiece.
